- Abstract
- A selection of representative definitions of information is drawn from information science and related disciplines, and discussed and compared. Defining information remains such a contested project that any claim to present a unified, singular vision of the topic would be disingenuous. Seven categories of definitions are described: Communicatory or semiotic; activity-based (i.e., information as event); propositional; structural; social; multitype; and deconstructionist. The impact of Norbert Wiener and Claude Shannon is discussed, as well as the widespread influence of Karl Popper's ideas. The data-information-knowledge-wisdom (DIKW) continuum is also addressed. Work of these authors is reviewed: Marcia J. Bates, Gregory Bateson, B.C.

- Abstract
- An analogy is established between the syntagm and paradigm from Saussurean linguistics and the message and messages for selection from the information theory initiated by Claude Shannon. The analogy is pursued both as an end in itself and for its analytic value in understanding patterns of retrieval from full-text systems. The multivalency of individual words when isolated from their syntagm is contrasted with the relative stability of meaning of multiword sequences, when searching ordinary written discourse. The syntagm is understood as the linear sequence of oral and written language. Saussure's understanding of the word, as a unit that compels recognition by the mind, is endorsed, although not regarded as final. The lesser multivalency of multiword sequences is understood as the greater determination of signification by the extended syntagm. The paradigm is primarily understood as the network of associations a word acquires when considered apart from the syntagm. The restriction of information theory to expression or signals, and its focus on the combinatorial aspects of the message, is sustained. The message in the model of communication in information theory can include sequences of written language. Shannon's understanding of the written word, as a cohesive group of letters, with strong internal statistical influences, is added to the Saussurean conception. Sequences of more than one word are regarded as weakly correlated concatenations of cohesive units.

- Abstract
- Does information science have a theory of information? There seems to be a tendency within information science to seek a theory of information, but the search is apparently unproductive (Hjoerland, 1998; Saracevic, 1999). This review brings together work from inside and outside the field of information science, showing that other perspectives an information theory could be of assistance. Constructivist claims that emphasize the uniqueness of the individual experience of information, maintaining that there is no information independent of our social practices (Cornelius, 1996a), are also mentioned. Such a position would be echoed in a symbolic interactionist approach. Conventionally, the history of attempts to develop a theory of information date from the publication of Claude Shannon's work in 1948, and his joint publication of that work with an essay by Warren Weaver in 1949 (Shannon & Weaver, 1949/1963). Information science found itself alongside many other disciplines attempting to develop a theory of information (Machlup & Mansfield, 1983). From Weaver's essay stems the claim that the basic concepts of Shannon's mathematical theory of communication, which Shannon later referred to as a theory of information, can be applied in disciplines outside electrical engineering, even in the social sciences.

- Abstract
- The concept of information as we use it in everyday English, in the sense of knowledge communicated, plays a central role in contemporary society. The development and widespread use of computer networks since the end of World War II, and the emergence of information science as a discipline in the 1950s, are evidence of this focus. Although knowledge and its communication are basic phenomena of every human society, it is the rise of information technology and its global impacts that characterize ours as an information society. It is commonplace to consider information as a basic condition for economic development together with capital, labor, and raw material; but what makes information especially significant at present is its digital nature. The impact of information technology an the natural and social sciences in particular has made this everyday notion a highly controversial concept. Claude Shannon's (1948) "A Mathematical Theory of Communication" is a landmark work, referring to the common use of information with its semantic and pragmatic dimensions, while at the same time redefining the concept within an engineering framework. The fact that the concept of knowledge communication has been designated by the word information seems, prima facie, a linguistic happenstance. For a science like information science (IS), it is of course important how fundamental terms are defined; and in IS, as in other fields, the question of how to define information is often raised. This chapter is an attempt to review the status of the concept of information in IS, with reference also to interdisciplinary trends. In scientific discourse, theoretical concepts are not true or false elements or glimpses of some element of reality; rather, they are constructions designed to do a job in the best possible way. Different conceptions of fundamental terms like information are thus more or less fruitful, depending an the theories (and in the end, the practical actions) they are expected to support. In the opening section, we discuss the problem of defining terms from the perspective of the philosophy of science. The history of a word provides us with anecdotes that are tangential to the concept itself. But in our case, the use of the word information points to a specific perspective from which the concept of knowledge communication has been defined. This perspective includes such characteristics as novelty and relevante; i.e., it refers to the process of knowledge transformation, and particularly to selection and interpretation within a specific context. The discussion leads to the questions of why and when this meaning was designated with the word information. We will explore this history, and we believe that our results may help readers better understand the complexity of the concept with regard to its scientific definitions.

- Einen interessanten Vorschlag machen schließlich Ceslav Brukner und Anton Zeilinger von der Universität Wien. Ganz in von Weizsäckers Sinn, die Naturwissenschaft auf Ja-Nein-Aussagen zurückzuführen, streben sie nach einer Herleitung der Quantentheorie aus der Informationstheorie. Ihr Ausgangspunkt ist die Annahme, dass jedes physikalische Objekt einen endlichen Informationsgehalt hat. Da diese Information aber nicht ausreiche, um die Resultate aus allen möglichen Messungen festzulegen, könne eine bestimmte Messung nicht mehr mit Sicherheit vorhergesagt werden. Der Indeterminismus der Quantentheorie ist damit auf ein fundamentaleres Prinzip zurückgeführt. Viele Autoren heben die Bedeutung von Weizsäckers Fragen und Antworten als Quelle der Inspiration und als Herausforderung an die etablierte Wissen schaft hervor, die in ihrer Vorausschau noch nicht an ihr Ende gekommen sei. Dem ist wenig hinzuzufügen."
